Why in the scene when they have Jack Jr's birthday they don't show the face of Julia Roberts they only show her hands and chest?

In the scene of Jack Jr.'s birthday, Julia Roberts' face is not shown to create a sense of mystery and emotional distance, emphasizing her character's internal struggles. By focusing on her hands and chest, the filmmakers invite the audience to feel her tension and anxiety without revealing her full expression, enhancing the dramatic impact. This technique allows viewers to interpret her feelings through body language, making the moment more intimate and poignant.
